目的:分析小細胞肺癌(small cell lung cancer,SCLC)的CT表現(xiàn)特點,以提高對該病的認識。方法:收集有CT和臨床資料并經(jīng)病理證實的SCLC 60例,回顧性總結分析CT影像特征。結果:中央型肺癌47例,CT表現(xiàn)為肺門分葉狀結節(jié)或腫塊,伴阻塞性肺炎11例(23.4%),阻塞性肺不張5例(10.6%),42例(89.4%)伴有縱隔淋巴結腫大,36例行CT增強,其中32例腫塊和淋巴結均勻強化。13周圍型SCLC中,9例腫大的肺門、縱隔淋巴結較肺內腫瘤大。結論:SCLC CT主要征象以肺門區(qū)實性腫塊為主,多伴有肺門、縱隔淋巴結轉移,支氣管阻塞征象出現(xiàn)較晚。
目的:探討鼻咽纖維血管瘤術前栓塞的應用價值。方法:17例鼻咽纖維血管瘤患者,單純手術摘除10例,術前3天進行數(shù)字減影血管造影(DSA)檢查及血管內栓塞術7例。結果:7例術前栓塞組術中出血200～700mL,平均430mL;輸血0～550mL;10例單純手術組出血550～1430mL,平均1200mL,輸血350～1200mL。術前栓塞組出血量和輸血量較單純手術組顯著減少。結論:術前瘤體栓塞治療鼻咽纖維血管瘤是安全有效、理想的術前輔助治療手段。
胰腺導管內乳頭狀黏液性腫瘤是一種臨床上少見的發(fā)生于胰腺導管上皮細胞腫瘤，近年來對該病的報道逐漸增多，現(xiàn)著重介紹其臨床病理學、常用影像學表現(xiàn)及方法比較、影像學提示腫瘤惡性的因素及鑒別診斷，旨在提高對其影像學認識。
【摘要】 宮頸癌的發(fā)病率居國內女性生殖系統(tǒng)惡性腫瘤的首位。臨床檢查以婦科檢查為主，有一定的主觀性和局限性。陰道鏡下行宮頸組織活檢病理學檢查，對宮頸癌前病變較為實用，準確率較高。因此，宮頸組織活檢病理學檢查是確診宮頸癌的金標準。B型超聲、CT及MRI影像檢查在宮頸癌的診斷、分期及治療計劃制定和療效評價中起著越來越重要的作用?，F(xiàn)就各種影像學檢查在宮頸癌中的診斷及分期予以綜述。
【摘要】 目的 探討系統(tǒng)性紅斑狼瘡腦?。⊿LEE）的磁共振成像（MRI）特征和診斷價值。 方法 回顧性分析2007年1月-2009年7月間18例SLEE的臨床表現(xiàn)及MRI特征。 結果 18例患者MRI檢查的顱腦陽性率為88.88%（16/18），腦部MRI表現(xiàn)為:①15例為多發(fā)病灶，局灶者1例。②雙側大腦半球、基底節(jié)區(qū)及小腦半球腦實質內長T1、長或稍長T信號，DWI及EPI成像上呈高或稍高信號，灰白質均可受累，分布無規(guī)律性。③增強MRI掃描9例，其中5例呈斑片狀強化，4例無明顯強化。④腦梗死12例，腦出血4例。合并腦水腫9例，腦萎縮7例。 結論 SLEE的MRI表現(xiàn)多樣，結合臨床資料，MRI可以作出診斷?！続bstract】 Objective To investigate the magnetic resonance imaging (MRI) features of systemic lupus erythematosus encephalopathy (SLEE) and its diagnostic value. Methods The clinical data and MRI images of 18 patients with SLEE admitted from January 2007 to July 2009 in our hospital were analyzed retrospectively. Results Positive findings were found in 16 patients (88.88%). MRI findings of SLEE were the following: ①A Total of 15 patients were with diffuse lesions, one patient was with focal lesions. ②Cerebral hemisphere involvement and bilateral caudate long T1 and long or slightly long T2 signal were intensive in the brain parenchyma, and appeared as hyper-intensity or slightly hyper-intensity on DWI and EPI. Grey and white matters were involved often and irregularly distributed. ③The results of 9 patients by enhanced MRI showed that 5 patients were with patchy enhancement and 4 were without enhancement. ④Of the 16 positive patients, 12 were with cerebral infarction and 4 with cerebral hemorrhage, while 9 patients were complicated with cerebral edema, and 7 patients were with cerebral atrophy. Conclusion MRI manifestations of SLEE are various. Combined with clinical data, MRI can diagnose SLEE exactly.
目的:探討單發(fā)腦轉移瘤的CT和MRI診斷價值。方法:回顧性分析37例經(jīng)手術病理證實或臨床綜合診斷確診的單發(fā)腦轉移瘤的CT和MRI表現(xiàn)。結果:病灶位于幕上31例,分布于皮髓質交界區(qū)21例。囊實性22例,實性9例,囊性6例。不規(guī)則環(huán)形強化13例,結節(jié)形強化7例,囊實形強化15例,均勻強化2例。病灶直徑gt;1.0 cm時瘤周水腫常較明顯。結論:單發(fā)腦轉移瘤的CT、MRI表現(xiàn)具有一定的特征,增強掃描對診斷單發(fā)腦轉移瘤有重要價值。
